Throughput (business)

Throughput is the movement of inputs and outputs through a production process. Without access to and assurance of a supply of inputs, a successful business enterprise would not be possible.[1][2]

Overview

In the business management theory of constraints, throughput is the rate at which a system achieves its goal. Oftentimes, this is monetary revenue and is in contrast to output, which is inventory that may be sold or stored in a warehouse. In this case, throughput is measured by revenue received (or not) at the point of sale—exactly the right time. Output that becomes part of the inventory in a warehouse may mislead investors or others about the organizations condition by inflating the apparent value of its assets. The theory of constraints and throughput accounting explicitly avoid that trap.

Throughput can be best described as the rate at which a system generates its products or services per unit of time. Businesses often measure their throughput using a mathematical equation known as Little's law, which is related to inventories and process time: time to fully process a single product.

Basic formula

Using Little's Law, one can calculate throughput with the equation:


where:

If you solve for R, you will get:
